Section: Hyperlinked text and hyperlinked commands
The last hyperlink that was set is recorded in two global indexed text variables:
the hyperlinked text
the hyperlinked command
These variables are not needed in normal usage, but they may be useful in communicating between routines.
Note that it is possible to do something other than paste a command in response to hyperlink input. See the Systematic Derangement of the Inner Compass example below.
